Struct CBackend

#[repr(C)]
pub struct CBackend<SB, GPA, GFD, IC, MC> { /* private fields */ }

Implementations

impl<SB, GPA, GFD, IC, MC> CBackend<SB, GPA, GFD, IC, MC>

where SB: Fn(*mut c_void) -> bool, GPA: Fn(*mut c_void, *const c_char) -> *const c_void, GFD: Fn(*mut c_void, &mut u32, &mut u32), IC: Fn(*mut c_void) -> bool, MC: Fn(*mut c_void),

pub fn new( data: *mut c_void, swap_buffers: SB, get_proc_address: GPA, get_framebuffer_dimensions: GFD, is_current: IC, make_current: MC, ) -> Self

The lifecycle of this object must match the OpenGLContext lifetime and thus is unsafe to create.

Trait Implementations

impl<SB, GPA, GFD, IC, MC> Backend for CBackend<SB, GPA, GFD, IC, MC>

where SB: Fn(*mut c_void) -> bool, GPA: Fn(*mut c_void, *const c_char) -> *const c_void, GFD: Fn(*mut c_void, &mut u32, &mut u32), IC: Fn(*mut c_void) -> bool, MC: Fn(*mut c_void),

fn swap_buffers(&self) -> Result<(), SwapBuffersError>

Swaps buffers at the end of a frame.

unsafe fn get_proc_address(&self, symbol: &str) -> *const c_void

Returns the address of an OpenGL function.

fn get_framebuffer_dimensions(&self) -> (u32, u32)

Returns the dimensions of the window, or screen, etc.

fn is_current(&self) -> bool

Returns true if the OpenGL context is the current one in the thread.

unsafe fn make_current(&self)

Makes the OpenGL context the current context in the current thread.
